Some 25,000 investors and landlords have signed up to receive a free expert guide from Zoopla in just over a week since launch.
Known as a 'Zooploma', the two week email programme provides property guides, expert advice and inspirational stories.
The 'Investor Zooploma' follows the successful launch of similar programmes for first-time buyers, homemovers and renters.
Last month, the portal revealed that 275,000 people had subscribed to receive the email guide on moving home.
The ‘Zooploma’ consists of a series of digest emails, delivered over two-weeks, followed up by a monthly update. It is designed to help investors and landlords 'stay on top of the rental market' and 'make the most from their property investments'.
Zoopla says the guide, which covers areas such as best practice, investor hotspots and legal issues, is suitable for both new and experienced buy-to-let landlords and investors.
"Buy-to-let investors are a key audience to us at Zoopla, which is why we have invested in developing a tailored ‘Zooploma’ designed to support them, and as a result, support agents, too," says Adam Knight, head of CRM at Zoopla.
"The world of an investor can be a complex one, with considerations to be taken on topics such as financial liabilities and also the best locations to invest."
Knight says he hopes the ‘Zooploma’ can help investors to take advantage of the stamp duty holiday before it expires next March.
